Definitions

• the present invention relates to the improvement of a system of dental implants intended to be fixed in the jaws to support an artificial tooth.
• REPLACEMENT SHEET The state of the art shows that it is possible to improve the performance of existing implants, to the extent that whatever the type, no implant simultaneously exhibits the qualities of ease of positioning, of simplicity of use, precision positioning of the stumps.
• the present invention relates to an implant-support system which is easy to set up and which allows the support to be oriented with great precision.
• the implant assembly stump is done by multiple indexing, the implant comprising an xn female sides and the stump a n male sides, which implies xn positions of the stump on the implant, (with x> 1). This is explained by the fact that any polygon is impactable in a polygon comprising a multiple of numbers of sections.
• stumps have male multipans offset from the original position, which makes it possible to multiply the number of desired positions.
• the industrial application of this invention is to propose a certain number of stumps comprising male multipans of different positions that the user can use as desired.
• the foundation implant is of cylindrical shape threaded or smooth to impact. It is dug in its center of the female multipans in which the male multipans of the stump will be fixed.
• the stump also comprises a male multipan base, a transgingival part positioned relative to the axis of the implant at a predetermined angle.
• the implant and the stump are therefore assembled by the multipan, which allows them to be embedded perfectly in one another.
• the abovementioned stump comprises the xn female sides and the implant comprises the n male sides.
• Figures la and lb show a threaded or impacted implant.
• Figures 2a and 2b show a stump to be sealed and screwed onto and into the implant.
• REPLACEMENT SHEET Figure 3a illustrates a bottom view of a six-sided stump, and Figure 3b shows a stub with offset hexagon
• Figure 3c is a top view of a 12-sided implant.
• Figures 4a and 4b respectively show the 2 stumps of Figures 3a and 3b impacted in the implant.
• FIG. 5 thus represents the 24 possible positions of the stump in the implant.
• FIGS. 6 and 7 illustrate an implant system
• Figure 8 shows an implant supporting a straight stump.
• FIG. 9 represents an inclined implant and an angled stump recovering the verticality.
• Figures 1a and 1b show the foundation implant of cylindrical threaded (2) or smooth to impact (3) shape. It is finished in its apical segment in a half-sphere (4), thus allowing a good distribution of the stresses.
• This implant has in its upper segment a smooth neck (5) which promotes better hygiene against bacterial plaque in the event of absorption.
• the threaded (2) or smooth (3) part of the implant is provided with vertical grooves (6) and treated by microblasting, promoting anti-rotation and osseointegration.
• this implant has a tapped cylindrical cavity (7), intended to receive the lower part of the stump (8) or the fixing screw (9).
• the upper opening (10) is combined with a 12-point female mechanism (1 1) in which the male 6-point (12) will be impacted.
• the prosthesis support fixed to the foundation implant and represented by FIGS. 2a and 2b, is generally composed of 4 elements: a lower part (8) intended to be placed in the internal threaded part of the implant, (7 ) a base (12) provided with a male multipan intended to be fixed in the female multipan (1 1) of the implant, a conical gingival part (13), a transgingival part consisting of a long cone positioned relative to the base at a predetermined angle (14) (15 or
• this cone can have different diameters and lengths.
• the stump is sealed on the foundation implant in its lower part. As illustrated in Figures 2a and 6, this cylindrical part has a groove of revolution (15) chamfered at its lower end, helping the extraction after gluing.
• the stump can be fixed to the implant by a transfer screw called the assembly screw (9).
• the stump rotation on the implant is done by indexing 360 ° / 12, which is equivalent to a rotation of 30 °.
• the number of positions doubles by using another stump whose polygon is offset from the original polygon.
• FIG. 3b illustrates a stump comprising an indexing offset by 15 °. The user will therefore be able to choose the orientation that best suits him in relation to the two stumps and 24 positions offered ( Figure 5). This system therefore quadruples current possibilities.
